Why Your Tankless Toilet Has Weak Flushes and How to Fix It

A tankless toilet is a modern toilet fixture that not only saves water and is environmentally friendly but also offers a better user experience. If you encounter weak flushing with a tankless toilet, here’s how to address the issue.

How to Handle Weak Flushing in a Tankless Toilet

1、Check Water Supply

The flushing mechanism of a tankless toilet relies on the pressure provided by the water supply. Therefore, when you find that the toilet is flushing weakly, the first step is to check if the water supply is functioning normally. Turn on a nearby faucet to check the water flow. If the water flow is normal, there may be other issues.

2、Clean Clogged Flush Holes

The flush holes inside the tankless toilet are responsible for washing away waste. If these flush holes are clogged, it will lead to weak flushing. The solution is to use a specialized toilet cleaner, pour it into the bowl, let it sit for a while, and then scrub with a toilet brush.

3、Adjust Water Flow Control Valve

The water flow amount in a tankless toilet can be adjusted. If flushing is weak, you should check whether the water flow control valve is set correctly. Refer to the toilet's manual to locate the water flow control valve and make adjustments. Generally, increasing water flow can enhance flushing power.

4、Replace the Flush Valve Core

The flush valve core in a tankless toilet is a crucial component. If it has been in use for a long time or is of poor quality, it can result in weak flushing. In this case, consider replacing the flush valve core. Seek professional help or purchase an original manufacturer’s flush valve core for replacement.

5、Clear Clogs in the Water Valve

The water valve in a tankless toilet is also a key component. If the water valve is clogged, flushing will be weak. The solution is to turn off the water supply, then disassemble the water valve for cleaning. Soak the valve in a cleaning solution for a while, then scrub it with a brush.

If none of the above methods resolve the issue, it may be due to insufficient water pressure. You may need to contact the water supply company to check the water supply situation. If the water pressure is inadequate, consider installing a booster device to increase the pressure and thereby resolve the weak flushing issue. If you are not familiar with repair procedures, it is advisable to seek professional assistance. You can contact the tankless toilet supplier or a home repair service for professional maintenance.

Summary:

This concludes the discussion on handling weak flushing in a tankless toilet. Weak flushing in tankless toilets is a common issue, but it can be resolved through some simple troubleshooting methods. When encountering weak flushing, first check the water supply and pressure, then proceed with various maintenance actions like cleaning flush holes, adjusting the water flow control valve, or replacing the flush valve core.
